Strange Sounds Coming from Your AC

Strange Sounds Coming from Your AC

It seems like there are always strange noises happening inside your home — creaking floorboards, rattling doorknobs, and the occasional moments of a lack of sound coming from the kid’s rooms. While some sounds may worry you and others don’t, you should be a bit concerned if you start to hear strange sounds coming from your air conditioner. Some of those sounds may include:


Sometimes, your outdoor condenser unit can start to make buzzing noises while it runs. This can be due to a number of issues, such as:

  • Debris in or around the unit
  • Loose or imbalances fan blades
  • Loose or failing motor
  • Dirty air filter
  • Refrigerant leak

These are just some of the reasons your unit could be buzzing, so it’s essential to have the unit inspected quickly if you notice this sound.

While a humming noise coming from your unit isn’t too bad of a sign, but it does often signal that something is amiss inside your unit. Often, humming can occur if something is loose in your unit, and, although this won’t cause any immediate harm, ignoring the issue could lead to bigger problems.


This noise typically happens when there is a loose component in your air conditioner. Loose parts can become dislodged and cause bigger problems, while loose electrical components can make for a malfunctioning unit or other dangerous problem. You may be able to check the unit yourself, but it’s also wise to just have a professional technician inspect your unit and make any necessary repairs.
